Review: ROMOSS 10000mAh Aluminum Power Bank

We’ve reviewed Romoss products in the past – and most of those have been portable power banks. However, this brand continues to impress and the company behind the hardware somehow continues to improve with each generation of devices.

This latest device I’ve been testing is the 10000mAh power bank. Its a bit heavier than those I’m used to testing, but it still fits in the hand. The extra heft is due to the enormous battery capacity that allows it to charge two devices at once.

This is an awesome power bank for those that either currently don’t have one, or for those looking for a portable power bank that can charge two devices at once with lots of varying port options.

Incidentally, we’ll be giving one of these away (among other things) during the IT/Dev Connections 2017 raffle in a few weeks.

Amazon has these for around $25: ROMOSS 10000mAh Aluminum Power Bank
